Just finished OA bath on this kuwahara.  After the parts were done soaking, i rinsed them off, and used "Barkeepers Friend" stainless/chrome powder polish (in ajax type thing) and a toothbrush, little water along all the welds and hard to reach areas to remove the rust.  Worked awesome.

FWIW, I am 99% sure that "Barkeepers Friend" is OA. Just thought I'd mention it.

half an ace hardware OA crystals can, about 6 oz of crystals, into a Christmas wrapping container, about 6-8 gallons of water. Normally 8 hours will clean up parts, but the gusset never cleaned up so i left it in to keep trying. I kept removing the yellow substance, but the rust in the gusset never yellowed. Here it is, less than half of the nickel is still good (left side), half is tarnished, and after heavy buffing on a wheel, still looks like crap. Feels smooth, but looks like dung.

Half a can? I used three table spoons and it worked just fine. Might be a little heavy on the powder.

That turned out great. Thatll sure look sweet when built

Didnt realize this is something you can do at home!!!!!!

10 bux for a tub of acid where im at

dts123, your bike turned out well.  Barkeepers is definitely an option for anyone who wants to clean a bike.  It combines the use of OA with a hands on approach

When I do an OA bath on a bike, my actually "hands on" labor time is about an hour.  That is disassembly, Simple Green cleaning, OA bath wiping, rinsing, and spraying rust inhibitor inside the parts.  Like I have said from the beginning, the greatest thing about an OA bath is the OA bath is doing all the work.

CMB, Thanks and I agree with you about the ease of OA if you have the place to do it, never tried it myself but the results Ive seen in the museum show for it.  I just was worried to try OA with kids and a dog running around and neighbor kids always in my garage.  My bike, I thought was a lost cause till I found this thread and a few others.  So many great tips in here.

I understand about the concerns.  Again, your bike turned out great...a very nice save if you thought it was a "lost cause".  I had a longer response earlier, but thought it was too wordy.  Here is part of what I took out:

But, a person has to choose what is right for them.  If someone wants to take a more hands on approach and doesn't mind doing the labor, then Barkeeper's Friend or something similiar would be ideal for them.  If someone wants something less laborious, then a bath is right for them.  In the end, all that really matters is that the outcome is acceptable.  The method to get there is minor.

That is why Wired's "Best of Restoration" sticky is so awesome.  He combined all the different posts that people have made, which allows for a person to look at those with ease and choose their best option.

I just wanted to give you my complete thought and let you know I wasn't trying to say anything negative about your work.  It turned out great and that is all that really matters.

oxalic bath- take the little tub of it, rub it all over your body in the shower

Can I use this on a redline mx2 that has been stripped?  I just stripped paint off of this f/f set I bought.  The paint was in terrible shape and had rust in scratched paint areas.  Unfortunately, the paint stripper i used must have been corrosive, because now the entire frame has a thin layer of rust.  I am concerned about using the OA process on a non-chrome bike.  Will it work?

I was going to send it off to Chip to be powdercoated.  Not sure if I should just ship as is or OA then ship.

This rocks! Now I am gonna hunt for a rust bucket just to experiment with this...A W E S O M E

Does anyone on this site live in Canada? I'm having trouble finding OA in Vancouver. Home Depot/Rona don't carry it. It doesnt look like this particular brand distributes up here. Anyone know how I can get my hands on it, other than eBay etc?

Is it eBay with which you have a problem with or on-line in general?   You can also pick it up on amazon.com or chemistry.com.

Barkeepers Friend has OA in it but it's pretty weak.  Also check for Wood Bleach....it's primary ingredient is OA.

I am in same boat here and bar keepers friend is only OA I can find locally and not seeing a change after 12 hours at ALL.  Any idea how much needs to be used, any one tested with this product ??  I've been adding slowly but still moving like in this post as I dont know how strong his is compared to bar keepers friend etc. but agree it is weak.  how much do I use, any ideas ??  or HOW much weaker than wood bleach ??  Going to go sprinkle more in

d-

Are you doing a bath with Barkeeper's?  If so, I think it would take a lot of it.  I would use it directly on the material.  As far finding OA, try paint stores.  Like Monster-Robot said, it may be called "Wood Bleach".  You can also try an independent pharmacy to see if they can order it for you.

I found this online, and it looks like it would be a total cost $40 to buy and ship 5 lbs of OA to Vancouver, Canada.
